Title: Contenant pour dispositif electrique utilisant une pile metal-air
Inventor: BENNETT LEONARD
IPC: H01M2/10
Filed: 1998-04-13
Abstract: L'invention a trait à un boîtier hydrorésistant (6) pour dispositif électrique, un mouvement électrique pour montre-bracelet par exemple, alimenté par une pile classique zinc-air à intensité élevée. Une ouverture de taille réduite (11) dans la paroi du boîtier ralentit l'entrée et la sortie de vapeur d'eau et ce, dans le but d'accroître la durée utile de la pile. C'est d'ailleurs plutôt cette ouverture qui limite le débit d'oxygène vers la cathode de la pile que les orifices d'admission d'air de la pile elle-même. Une membrane hydrophobe perméable au gaz (45) laisse passer l'air et la vapeur d'eau vers l'ouverture sans laisser passer l'eau en phase liquide.

Title: Inexpensive electronic transformer
Inventor: MESZLENYI IVAN
IPC: H02M3/338
Filed: 1999-11-09
Abstract: A Schmitt oscillator driving a pair of switching elements via a high current inverting buffer and the pulse train obtained at the junction of said switching elements is fed in series with a resonant capacitor and the primary of an isolation transformer having a primary and secondary winding and having an appreciable amount of leakage inductance transferred to the primary so as to achieve resonant transitions of the voltage waveforms at the junction of said switching elements. To ensure resonant transitions said isolation transformer is equipped with a gap sufficient to achieve aforesaid mode of operation. The voltage developed on said resonant capacitor is fed to a voltage doubler to produce a DC voltage proportional to the load current, if DC voltage obtained as described is greater that the lower threshold of Schmitt oscillator a timing resistor from the junction of said switching elements will increase the frequency so as to limit the current that can be obtained on the secondary.

IPC: F41B11/00
Filed: 1998-08-24
Abstract: An improved ball projecting apparatus which utilizes air pressure supplied by a separate and independent source flowing air, such as a leaf blower, to project balls. More specifically, it comprises a barrel (10) of tubular form defining a linear air discharge axis. The barrel is attached on one end to the source of flowing air (11). A barrel hole (12) is formed in the barrel wall.  Attached to the barrel is a tumbler casing (14). The casing has a hollow tubular formation. It has an entry hole (16) and a feed hole (19) formed on its wall directly opposite each other. The tumbler casing is attached and sealed at its feed hole to the barrel hole creating a path or feed port into the barrel. Revolution of the tumbler feeds balls into the barrel while continuously maintaining an obstacle to air loss through the barrel hole.
Patent CA-2303581-A1 (CA)
Inventor: DEMERDJIEV PETER GUEORGIEV
IPC: A47C7/00
Filed: 2000-03-29
Abstract: An office chair base is the bottom part of every office chair securing its vertical stability and providing free movement in a horizontal plane perpendicular to the axis of the vertical support column.     The movement in all existing office chair bases is effectuated by means of using casters.  In this invention the casters are eliminated and replaced by balls located in grooves inside a ribbed injection molded base. The balls are kept into position by two wire rings with different diameters, which snap fit into a set of grooves in the injection molded base.    The result is a smoother movement, since the loads are transmitted directly to the balls and a better load distribution to the underlying surface, since there are six balls compared to five castors for a standard office chair base.

Title: Method for creating polynucleotide and polypeptide sequences
Inventor: VOLKOV ALEXANDER
IPC: C12N15/09
Filed: 1998-12-04
Abstract: The invention provides methods for evolving a polynucleotide toward acquisition of a desired property. Such methods entail incubating a population of parental polynucleotide variants under conditions to generate annealed polynucleotides comprising heteroduplexes. The heteroduplexes are then exposed to a cellular DNA repair system to convert the heteroduplexes to parental polynucleotide variants or recombined polynucleotide variants. The resulting polynucleotides are then screened or selected for the desired property.

Title: Low noise encoding and decoding method
Inventor: YU HAOPING
IPC: H04N19/85
Filed: 1997-12-23
Abstract: An adaptive digital image processor (22) precedes an MPEG2 encoder (24). The processor receives a high definition (1920 by 1080 pixels per image) video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering (223) to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled (226) to create a lower resolution hybrid signal (1280 by 1080 pixels per image). A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.

Title: Method for determining dna nucleotide sequence
Inventor: HAYASHIZAKI YOSHIHIDE
IPC: C12Q1/68
Filed: 1999-01-22
Abstract: A method for determining the base sequence of a target DNA fragment which comprises amplifying the DNA fragment while forming a nucleic acid transcript by using an RNA polymerase with the use of the thus amplified DNA fragment as a template in the presence of a nucleic acid transcript terminator, and then analyzing the nucleic acid transcript thus obtained, wherein the amplification of the target DNA fragment and the formation of the transcript are effected isothermally. The amplification of the target DNA fragment and the formation of the transcript are effected at around ordinary temperature and the target DNA fragment can be amplified by the strand replacement/amplification method. According to this novel method, a DNA can be sequenced by effecting the amplification of the target DNA fragment and the formation of the nucleic acid transcript at the same time without resort to any thermostable RNA polymerase.

Patent CA-2327248-A1 (CA)
Inventor: STROMBERG C BERTIL
IPC: D21C9/10
Filed: 2000-12-01
Abstract: An environmentally friendly (ECF), yet commercially viable, process produces fully bleached (typically having a brightness of over 89 or 90% ISO) cellulose pulp using a (ZEND) treatment. Typically pulp is produced in an essentially sulphur-free pulping process (such as an soda/AQ process), and is then treated by a D-EO-, D-EP-, or D-EOP-sequence before the (ZEND) treatment. Optional oxygen delignification may also be used, and subsequent elemental-chlorine-free bleaching sequences may also be employed, although normally not necessary since the pulp after the (ZEND) treatment has high brightness and good viscosity (e.g. over 21 cP).
